Specification of Letters Patent.

Patented Oct. 30, 1906.

Application filed. October 3, 1904- Serial No. 226,924.

To all whom it may concern:

Be it known that I, J OHN C. FOUNTAIN, a subject of the King of GreatBritain, and a resident of Parkhill, in the county of Middlesex, in the Province of Ontario, Canada, have invented a new and useful Exhaust-Condenser, of which, the following is a specification.

The object of this invention is to supply an improved device for condensing exhauststeam and thendelivering it to and causing sists of the improved construction and novel combination of parts of the same, as will be hereinafter first fully set forth and described and then pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of a device embodying my invention, in which the check-valves are shown in section. Fig. 2 is an enlarged detail side elevation I of the condensing-chamber. Fig. 3 is a central cross-sectional view of Fig. 2.

In the accompanying drawings, the numeral 21 designates a condensing-chamber, the inner face of a portion of which at the lower end is formed conical or tapers inward toward the lower end to form a valve-seat, as shown at a in Fig. 3.

22 designates a lateral water-inlet opening densed'steam outlet opening formed in the lower end of, said condensing-chamber 21.

24 designates a water-conducting pipe which is secured to the condensing-chamber 21 in the water-inlet opening 22, and 25 a valve with which said water-conducting pipe 24 is provided for the purpose of regulating the flow of water through said pipe 24 and to the condensing-chamber 21. 26 designates a screw-threaded opening formed in the upper end of said condensingchamber 21; 27, an adjustable sleeve, a portion of the outer face of which is screwthreaded, as shown at b, and said screwthreaded portion is fitted to, adapted to engage with, and be'adjusted back and forth in said screw-threaded opening 26 of the condensing-chamber 21; and part of said sleeve 27 extends inside and part outside of said condensing-chamber 21, and the outer face at the end of the part of said adjustable sleeve 27 which extends inside of said condensing-chamber is-beveled ofi, as shown at l c, to adapt it to fit tightly against the interior conical face or valve-seat a of said condensing-chamber 21.

28 designates an exhaust-steam-conducting' pipe which is secured to and o ens into the upper end of said adjustable s eeve 27 which, with the latter, conducts the exhauststeam into the condensing-chamber 21, and 29 designates a branch pipe extending from said exhaust-steam pipe 28 to carry off any excess of exhaust-steam that cannot be condensed in the condensing-chamber 21. The branch pipe 29 is preferably provided with a check-valve 29 to prevent ingress of air to the condensing chamber at periods when there is no excess of exhaust-steam.

30 designatesa conducting-pipe which extends from and communicates with said condensing-chamber 21 and the hot-water cham-- chamber 31 and the pump-cylinder 37; and

38 is a check-valve located in said pipe 36.

39 designates a pipe extending from and communicating with the pump-cylinder 37 and the steam-boiler 40. 41 designates a check-valve in said pipe 39.

42 designates a plunger-rod operating a plunger (not shown) in the pump-cylinder 37.

.The operation is as follows: First open the valve 34 to permit the exhaust-steam to pass from the exhaust-steam pipe 28 through the adjustable sleeve 27 into the condensingchamber 21, and from this condensing-chamber 21, through pipe 30, check-valve 32, branch pipe 33, and out through nozzle '35.

Then open the valve 25 to permit the water to flow from a reservoir (not shown) to the condensing-chamber 21, and this water flowing through the condensing-chamber 21 as it passes the end of said adjustable sleeve 27 condenses said exhaust-steam and creates a suction in the sleeve 27 and the exhaust steam being drawn through the pipe 28 by the suction thus created relieves the engine from the back pressure of said exhaust-steam, and as said exhaust steam becomes incorporated with and is condensed by the water it heats the latter, which heated water then flows through pipe 30 to the hot-water chamber 31. The valve 35 is then closed, so as to stop the flow of water through the pipe 33. In the event of an accumulation of water in the hot-water chamber 31 more than could be contained by the latter the valve 34 would be opened and said water would pass out through branch pipe 33. This pipe would in this case act as an overflow or permit the excess of water to escape and prevent back pressure of this water on the engine. This heated water is then pumped or drawn from the hot-water chamber 31 and delivered to the steam-boiler 40 by the plungerrod 42 operating a plunger (not shown) in the pump-cylinder 37. As the plunger-rod 42 commences to rise the check-valve 41 will instantly close and the check-valve 38 open, and, the condensing-chamber 21 and hotwater chamber 31 being located above the check-valve 38, the gravity of the water would assist in opening said check-valve 38, and the continuation of this upward movement would not only draw but permit the water to flow into the pump-cylinder 37. Thus the gravity of the water would assist the operation of the pump. Again, as said plunger-rod 42 commences to lower the pressure on the water would instantly close the check-valve 38 and open the check-valve 41, and the continuation of this downward movement would force the water into the boiler 40.

On the upward movement of the plungerrod 42 the check-valve 41 would instantly close and the check-valve 38 open to permit a fresh supply of water to flow and be drawn into the cylinder 37 and the operation hereinbefore described repeated, and so on until a sufficient supply of water had been delivered to the boiler.

By adjusting the sleeve 27 downward the conical outer face a of said sleeve and the inner conical face a of the .chamber 21 would be closer together, and consequently less water would pass between them, and an adjustment of said nozzle in the opposite direction would adjust said conical faces farther apart to permit more water to pass between them and past the end of the adjustable sleeve 27, and the more or less water passing the end of the adjustable sleeve 27 the greater or less suction there would be to draw the exhauststeam into the condensing-chamber 21, so that by this adjustment of the sleeve 27 a greater or less quantity of exhaust-steam is drawn into the chamber 21 as required or the lower beveled end 0 of the adjustable sleeve 27 may be adjusted tightly against the interior conical face or valve-seat a of the condensing-chamber and altogether shut off the supply of water if found advantageous or necessary.

If any derangement of the check-valves 4'1 and 38 should take place, the pressure in the boiler would force the water out of the hotwater chamber 31 into the pipe 30, where it would be checked by the eheck-valve 32, and under these circumstances the valve 34 would be opened and the water would then flow out of the branch pipe 33 and nozzle 35. This would prevent any ossibility of back pressure of this water on t 1e engine.

It will be readily understood that a valved branch pipe extending from the pipe 39 could be utilized to conduct the hot water to hot-water radiators located in the factory, warehouse, or oflices to heat these different departments if required.

As a result the device hereinbefore described provides a simple, strong, durable, inexpensive, safe, and efficient means for condensing exhaust-steam and delivering the condensed steam and water heated by said exhaust-steam to the boiler, and, said water being heated by said exhaust-steam before entering the boiler, the heat of the boiler is not materially affected by supplying water thereto.

While in the drawings forming part of this specification there is illustrated one form of construction embodying my invention which I prefer, it is understood that the elements therein shown may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit of my invention.
